An asteroid as large as a stadium is considered potentially dangerous by NASA and is predicted to approach Earth closely.

On Tuesday night, a large asteroid is predicted to approach Earth, and NASA is keeping a watchful eye.

According to NASA's Asteroid Watch Dashboard, the 2024 ON rocky object has a diameter of 950 feet and is considered "stadium-sized." It will be 621,000 miles from Earth on Tuesday night, which is relatively close.

Despite being classified as a "potentially hazardous object," Earth is unlikely to be hit by the asteroid.

Over the next two days, Earth will encounter five asteroids, but only one will come as close as 2024 ON. The four other asteroids will be between 1.1 to 3.9 million feet away from Earth, and three of them are approximately 51 feet in diameter, which is the size of a house.

On Wednesday, Earth will be passed by an asteroid measuring approximately 510 feet in diameter, which is named 2013 FW13.

NASA's Asteroid Watch Dashboard monitors "asteroids and comets that will come close to Earth." According to a data table, 2024 ON was moving at approximately 8.8 kilometers per second on Tuesday morning, which is equivalent to nearly 20,000 miles per hour.

The website explains that the dashboard shows the date of closest approach, approximate object diameter, relative size, and distance from Earth for each encounter.

"A potentially hazardous object is any object larger than 150 meters that can approach the Earth to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon), as displayed on the dashboard."
